Syphilis transmission can occur when infected lesions come in contact with the soft skin of the mucous membrane found inside the vagina, urethra or with an abrasion during vaginal, oral and anal sex, even if there is no sexual penetration.
Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. If it's not treated by a doctor, it can get worse over time and cause serious health problems. The infection can be active at times and not active at other times. When the infection is active, you have symptoms. When it's not active, you don't have symptoms, even though you still have syphilis.
